Yesterday or the code works with all-screen mode to switch each other, and there is a debugging. Constantly writing log, constantly tracking, after another bug, finally can always switch to window mode and full screen mode. In this process, I don't know how many times I have died, and the process of death of Windows2000 is not bad, or not to press the power to press the power supply. When switching from full screen mode to window mode, you must not perform single-step debugging, otherwise you will die there. However, there is no way, and there is still a need for a few times. This slowly improves, you can switch from full screen to window mode.
This feature is finally implemented, followed by another processing code that changes the size of the window, because all UIs are processed in the window mode, is related to the window size. Continue Coding ..................
